Polycarboxylate Superplasticizer can be used as a water-reducing and cement dispersant to apply cement concrete. It is used extensively in bridges, tunnels. high-rise buildings as well. Polycarboxylate Superplasticizer PCE Powder High perf…
When the same polycarboxylic acid sloughing agent is used but different cement is used, it is possible that this polycarboxylic acid sloughing agent has good compatibility with one kind of cement but poor compatibility with another cement, and when u…
Polycarboxylate superplasticizer is the third generation of high performance superplasticizer after common superplasticizer and superplasticizer.…
Because the steric hindrance of the extended polymer side chain effectively hinders the secondary agglomeration between cement particles, so the product has high dispersion performance and can maintain this performance for a long time to realize the…
Polycarboxylate superplasticizer has more advantages than traditional naphthalene and aliphatic superplasticizer in mixing high strength grade concrete, but its advantages of high water reduction cannot be brought into full play when the strength is…
Natural river sand has been exhausted after decades of large-scale mining, concrete production enterprises began to use machine-made sand as fine aggregate on a large scale.…
If the compatibility of polycarboxylate superplasticizer and cement is not good, the concrete mixture is prone to some problems, such as segregation, bleeding, greater slump loss, shorter setting time and so on, so that the concrete mixture can not b…
The wide application of mineral admixtures mainly derived from industrial solid wastes diversifies the composition of cementitious materials, which is one of the main characteristics of modern concrete.…
Adding polycarboxylate superplasticizer can make the compressive strength of precast concrete reach 40MPa grade at 8h to 18h.…
The impermeability of concrete is related to its porosity and pore structure.…
Polycarboxylate superplasticizer is based on unsaturated polymerizable monomers with active groups such as carboxyl group, sulfonic acid group, hydroxyl group and polyoxene group as raw materials.…
According to the different molecular structure, it can be divided into four generations of polycarboxylate series superplasticizer, the first generation is acrylic acid copolymer, the second generation is propylene ether type, the third generation is…
